Barcelona will have to do without Andres Iniesta when they face Arsenal in the Champions League on Wednesday after he injured his thigh in a Primera Liga game. The Spain international was substituted in the second half of Barcelona's 1-0 victory over Real Mallorca on Saturday after injuring a thigh muscle. He will need around 10 days to recover, Barcelona said on their official website on Sunday. He will not be able to play in the Spanish giants' clash away to Arsenal in the first leg of the Champions League quarter finals. Iniesta is also doubtful for the return leg, which will take on April sixth.
